## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stablesocial-facebook-post-comments-f968a9a0 -d '<json body>'
```

Example prompt: Can you pull all the comments from this Facebook post for me: https://www.facebook.com/SomeBrand/posts/1234567890 — I want to see what people are saying about it.

## When to prefer this

Use this endpoint when you need to retrieve comments from a specific Facebook post without setting up OAuth or a subscription. Ideal for one-off analysis, sentiment scraping, or monitoring public reactions to a Facebook post. Best suited when pay-per-request pricing is acceptable and no persistent API credentials are desired.

## Known failure modes

- Post URL or ID not found or invalid — returns error indicating bad input
- Post is private or restricted and not accessible — returns access/permission error
- Facebook rate limiting or blocking causes failure — returns upstream error
- Malformed request body — returns 400-style validation error
- Payment not fulfilled — returns 402 Payment Required
